Messages seeking comment were left with lawyers for the Trumps and James’ office.
The Attorney-General’s attempt to get testimony from the former president was reported in December,but the court filing was the first public disclosure that investigators were also seeking information from Ivanka Trump and Trump jnr.
Lawyers for the family have asked a judge who has overseen disputes related to the probe to quash James’ “unprecedented and unconstitutional” bid for their testimony.
Alternatively,they asked the judge to block the subpoenas until Manhattan’s district attorney finishes a related criminal probe that James joined last May.
This sets up a legal fight similar to one that played out last year after James’ office subpoenaed another Trump son,Eric.
Donald Trump sued James last month,seeking to end the investigation after she requested that he sit for a January 7 deposition. Trump’s lawsuit,filed in federal court,alleges that the probe has violated his constitutional rights in a “thinly veiled effort to publicly malign Trump and his associates”.
The latest court filing was the Attorney-General Office’s first public acknowledgement that it has previously subpoenaed Trump’s testimony.
